指定ssh非22端口并限速 ``` rsync -avz -e 'ssh -p 10000' --bwlimit=3072 mysql_backup_20180410.tar.gz 192.168.56.100:/data ``` 报错提示: ``` bash: rsync: command not found rsync: connection unexpectedly closed (0 bytes received so far) [sender] rsync error: remote command not found (code 127) at io.c(226) [sender=3.1.1] ``` 原因: 远端服务器没有安装rsync命令,使用rsync需要两端都安装rsync命令才行
